Abstract
An electrolytic generator is disclosed having three sealed compartments, separated by two spaced ion-permeable membranes, one being a cation exchange membrane and the other being an anion exchange membrane, having a cathode in one end compartment, adjacent to the cation exchange membrane, and an anode in the other end compartment, adjacent to the anion exchange membrane. A bipolar electrode is positioned in the middle compartment between the anion and cation exchange membranes. When the cell is filled with brine and energized, hydrogen is evolved from the cathode-containing compartment and a chlorine/chlorine dioxide mixture from the anode-containing compartment for use in bleaching or in treating bodies of water, such as, swimming pools, baths, reservoirs, sewage, etc. The anode, cathode and bipolar electrode are preferably flat plate electrodes, although other configurations, such as, cylindrical electrodes may be used. The generator is characterized by a rapid start up when energized with electricity.
